Abstract

The utility model provides an aluminum alloy mortise-tenon structure convenient to mount. The aluminum alloy mortise-tenon structure comprises an aluminum alloy body, a tenon and a mortise. The tenon comprises a tenon tongue and a tenon shoulder. The tenon tongue is in an arrow shape. The mortise is a wide-side-out channel which comprises two symmetric channel walls. The outer ends of the channel walls are fixed on the aluminum alloy body. The inner ends of the channel walls are not fixed. End heads of the inner ends are oblique faces. The widest part of the tenon tongue is lightly larger than the narrowest part of the mortise channel. Under the effect of external force, the widest part of the tenon tongue can penetrate through the narrowest part of the mortise channel. According to the mortise-tenon structure, the tenon can be clamped into the mortise conveniently, mounting is convenient and quick, stability is high, and deforming is not easy.

Description

A kind of aluminum alloy joinery and its construction easy for installation

Technical field

The utility model relates to a kind of joinery and its construction of aluminium alloy extrusions.

Background technique

The advantages such as aluminium alloy extrusions is solid owing to having, durable, light, are widely used in furniture and building material industry, and when utilizing aluminium alloy extrusions to be spliced into plane that area is larger or floor, conventionally all need to utilize joinery and its construction to splice.In prior art, the mounting type of conventional aluminum alloy joinery and its construction (see figure 3) can only be to adopt dislocation sleeve type, installation rate is slower, and tenon and tongue-and-groove in transportation or installation process because easily there is the problem of local deformation in extruding or collision, cause splicing more difficult or splicing after insecure, thereby affect installation quality and installation efficiency.

Model utility content

The technical problems to be solved in the utility model is to provide the aluminum alloy joinery and its construction of a kind of easy for installation, stable connection, the snap-in installation of employing.

For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of aluminum alloy joinery and its construction easy for installation, comprise aluminum alloy body, tenon and tongue-and-groove, and described tenon comprises joint tongue and tenon shoulder, described joint tongue is arrow shaped; Described tongue-and-groove is a passage wide outside and narrow inside, and described passage consists of two symmetrical conduit walls, and the outer end of described conduit wall is fixed on aluminum alloy body, and the inner of conduit wall is without fixing, and inner termination is inclined-plane; The widest position of described joint tongue is slightly larger than the narrowest place of tongue-and-groove passage, and under the effect of external force, the widest position of described joint tongue can be through the narrowest place of tongue-and-groove passage.

The joinery and its construction that technique scheme provides, can snap in tenon in tongue-and-groove easily, quick and easy for installation, and stability is high, not yielding.
